error message
 

I have a couple of files that a friend of mine programmed
using vba. I do not know anything about programming, but
when I try to open the excel files, I get an error message
that says, "Microsoft Visual Basic - Error accessing the
system registry". When I click ok, the error message goes
away, but the file will not open. Can someone please tell
me how I can get rid of this problem? Thanks.
